kontaktkeevituse/takistuskeevituse protsess/operatsioon, mille korral keevisõmblus tekib katteliitesse paigutatud detailide vahel neid kokku suruvate ja keevitusvoolu rakendavate rullelektroodide toimel keevituspunktide jadana (vt kontaktkeevitus; vrd punktkontaktkeevitus, reljeefkontaktkeevitus), a resistance welding process that produces coalescence at the faying surfaces of overlapped parts progressively along a length of a joint; the weld may be made with overlapping weld nuggets, a continuos weld nugget, or by forging the joint as it is heated to the welding temperature by resistance to the flow of the welding current (see: resistance welding; compare: resistance spot welding, resistance projection welding)
